ive got an 87 4runner that i crushed the fuel tank in twice so to remedy this problem i put a fuel cell in the back. i ran a aftermarket high pressure pump from it plumbed back into the factory lines problem is i want to use the factory wires to power the pump, im not using the gauge though how do i wire it to make it run without the sending unit pluged in i cant seem to get any fire to the pump.
